土方工程方案
1.編制依據
（1施工圖紙：基礎平面布置圖結-1。
（2《地基與基礎工程施工質量驗收規范》
《建筑工程施工質量驗收統一標準》
2.操作工藝
1）土方
開挖工程：先放好坡頂線、坡底線，經復測及驗收合格后開始開挖。
2）第一布先挖去槽中混凝土路面和下水管道，然后自西向東和自東向西程S型為兩臺挖土機開挖開挖時槽底留100MM厚土體由人工隨挖土機清理至-1.9米處。
3）土方開挖完畢后，測量人員隨即放出基地線和基槽釬探布置點位，開始進行基槽釬探施工。
4）釬探完成后進行基槽驗收，合格后在基底上放好槽邊線。
5）為防止雨水浸泡基槽底，沿基坑邊30CM外預挖50CM寬的臨時排水溝，且在轉角處社臨時技積水坑，坑內配置一臺抽水泵，隨時抽出坑內積水。
6）土方回填工程；填土前應將槽底或地平上的垃圾等雜務清理干凈�；靥钔恋暮恳刂圃诜秶�
Earthworks program
1. Preparation of the basis
(1 construction drawings: floor plans based on node -1.
(2 "foundation and basis for acceptance of construction quality"
"Building Construction Quality Check"
2. Operation Process
1) Earthwork
Excavation: First put away crest line, slope the bottom line, and the acceptance by the retest after excavation.
2) The first cloth first dredged tank concrete pavement and sewer, and then from west to east and from east to west, two-way S-type excavator for the excavation excavation bottom left 100MM thick soil dug by hand with earth to clear up to -1.9 meters.
3) The earth excavation is completed, the surveyors immediately release base line and the base tank filler point and probe arrangement to commence construction of foundation trench filler probe.
4) drill exploration based upon completion of acceptance slot, put away after passing trough the substrate edges.
5) The base bottom to prevent rainwater soaking along the pre-dug pit outside edge 30CM 50CM wide temporary drainage ditches, and temporary technology community in the corner water pit, the pit configuration a pump, keep water out of the pit.
6) The earth filling works; fill the former should be on the bottom or the horizon and garbage clean up chores. Backfill in the area to control the moisture content
